The 1851 census in the Isle of Man has at New Bond St. Douglas :-

Ellen Mcfie 31 Mariners Wife Isle of Bute
James, son 3 Douglas
Ellen, Dau. 5Mths Douglas

There was a marriage 1845 in Rothesay Bute between Eleanor Brown and James Mcfie but the parents of James age 3 are recorded in IGI as James Mcfie and Ellen Bridson. I wonder if there was a transcript error?

There was also a Margaret christened the same day as Ellen in 1853 with the same parents.

By 1881, also in Liverpool, a James Mcfie had married a Jane Doyle in Everton and had the following children,

William 5
Ellen 2
Hannah 5Mths

This James was aged 33, from the Isle of Man and living near the others.
